Description: Power Source
Information:
                                    The California Instruments Model 503T is a solid state, high
performance, low distortion power source that provides up to
500 VA the three phase power when used with the proper
California Instruments oscillator. The Model 503T Three
Phase Power Source is illustrated in Figure 1- 1. Full power
output is available in five different voltage ranges and
over the frequency range from.45 Hz to 5 KHz. The output
voltage range is normally determined at the factory prior to
shipment of the unit, however it can be accomplished in the
field, if required. The full power ranges are;
1) 23, 4 to 30 volts rms line-to-neutral in a three phase
output configuration. This provides 40* 5 volts to 52 volts
rms line-to-line at 167 VA per phase (500 VA total).
2) 35. 1 to 45 volts rms line-to-neutral in a three phase
output configuration. This provides 60. 6 volts to 78 volts
rms line-to-line at 167 VA per phase (500 VA total).
3) 58. 5 to 75 volts rms line - to-neutral in a three phase
output configuration. This provides 102 volts to 130 volts
rms line-to-line at 167 VA per phase (500 VA
..........total)...,.......................................................................................................
4) 105 to 135 volts rms line-to-neutral in a three phase
output configuration. This provides 182 volts to 234 volts
rms line-to-line at 167 VA per phase (500 VA total).
5) 105 to 135 volts rms single phase output at 500 VA.
The serial number tag, located on the rear of the Model 503T
Power Source, indicates the output voltage range which the
unit is wired for at the time of shipment.
